“My personal desire would be to prohibit entirely the use of alternating currents. They are as unnecessary as they are dangerous. I can therefore see no justification for the introduction of a system which has no element of permanency and every element of danger to life and property”

- Thomas Alva Edison, 1889

 

High density computer environments, utilizing Alternating Current (AC) power supply blade server technology, are presenting major challenges to owners and operators. Typical facility infrastructures cannot accommodate the added heat loads and reliability requirements of such installations.

 

Servers equipped with Direct Current (DC) power supplies, instead of AC power supplies:

operate with 20-40% less heat

● reduce power consumption by up to 30%

● increase server reliability

● offer flexibility to installations

● decrease maintenance requirements
